Chinese-American Female Scientists Study Artificial Skin Breakthrough Simulation Degree High Tactility Stronger

According to the report of the “Chinese Press”, the Chinese female scientist Shen Nan Bao of Stanford University has made persistent efforts on the basis of scientific research achievements in artificial skin, and developed a more transparent sensor skin with super elasticity so that the artificial electronic skin can have More natural skin feel. The study was published in the journal Nature Nanotechnology on October 23rd.

The newly developed artificial electron skin technology of Baozhan Nan team has super elasticity, twice the stretchability can make a large area of ​​artificial skin to be made simpler, and the transparent color also makes the artificial skin making the color simulation more realistic. The technology uses carbon nanotubes arranged in a spring-like manner to replace electrodes made of inorganic materials. It not only has the original conductive function, but also has twice the tensile and transparency.

This study is based on further refinement of Bao Zhe Nan's two artificial skin technologies in September 2010 and February 2011. The continuous development of artificial skin technology is expected to be widely used in prosthetics, robots, mobile phones and computer touch screens, automotive safety and medical devices.

Bao Zhenan is a Chinese young female scientist who has achieved brilliant achievements in artificial electronic skin and is one of the best female chemists in the United States. In September 2010, Bao Zhenan and his doctoral students published research findings on artificial skin materials that have attracted extensive attention in the research community. The so-called artificial skin material is a high-sensitivity flexible plastic film material that can simulate human skin. It is composed of highly sensitive electronic sensors. Artificial skin consists of many such sensors. In February 2011, Bao Zhenan and the team also developed the latest stretchable solar cells, which added new solar power functions to the artificial electronic skin to further improve it.

The new scientific research results published in the October 23 issue of "Nature Nanotechnology" were further improved on the two previous artificial skin technical achievements of the Baozhan Nan team, which not only retained the electronic skin but also perceived a butterfly resting on it. The sensitivity of the pressure, the ability to use solar energy to provide power automatically, has increased twice the ductility, and it is easier to create artificial skin that is close to human skin color in a transparent color.

The continuous development of artificial skin technology is expected to be widely used in many aspects such as touch display of artificial limbs, robots, mobile phones and computers, vehicle safety and medical devices. Bao Zhe Nan introduced that in real life, this tactile sensor can be applied to a very wide range. For example, nowadays skin transplants and the improvement of artificial limbs that do not have the ability to sense can all use this technology. With sensitive “tactility”, the future prosthetic limbs will resemble the patient’s original limbs. Another possible point is the steering wheel. If a tactile sensor is installed, the steering wheel can automatically sense the driver's abnormal driving and send a reminder when the driver is tired and not holding the steering wheel. This can also reduce traffic. ACCIDENT.

Bao Zhenan grew up in Nanjing and later immigrated to the United States to study chemistry at Illinois State University Chicago. In 1995, Baozhan Nan received a Ph.D. in chemistry from the University of Chicago, and then worked at Bell Labs. Since 2004, Baozhan Nan has joined Stanford University and is currently an associate professor of chemical engineering at Stanford University. (Wang Shuoyu)
